A test tube becomes cool to the touch.

Explanation:

The signs for an endothermic reaction would most likely be that a test tube becomes cool to touch. An endothermic reaction is a reaction in which heat is absorbed from the environment.

  • At the end of this heat change, the surrounding becomes colder.
  • Most endothermic reactions are always shown by the test tube becoming colder.
  • For exothermic reaction in which heat is given off to the surroundings, the tube should be hotter.

Difference between soft water and hard water in table
salantis [7]

Hard water can not be used for laundry while soft water can be used for laundry.

<h3>Types of water</h3>

There are basically two types of water, hard water and soft water. The following is a comparison of the properties of hard water and soft water.

  • Hard water do not form lather with soap while soft water forms lather with soap.
  • Hard water contains calcium and magnesium ions while soft water does not contain calcium and magnesium ions.
  • Hard water forms white patches when boiled in a kettle but soft water does not do that.

Hence hard water can not be used for laundry while soft water can be used for laundry .

Primary alcohol oxidation products
Yuliya22 [10]

write an equation to represent the oxidation of an alcohol.

identify the reagents that may be used to oxidize a given alcohol.

identify the specific reagent that is used to oxidize primary alcohols to aldehydes rather than to carboxylic acids.

identify the product formed from the oxidation of a given alcohol with a specified oxidizing agent.

identify the alcohol needed to prepare a given aldehyde, ketone or carboxylic acid by simple oxidation.

write a mechanism for the oxidation of an alcohol using a chromium(VI) reagent.

The reading mentions that pyridinium chlorochromate (PCC) is a milder version of chromic acid that is suitable for converting a primary alcohol into an aldehyde without oxidizing it all the way to a carboxylic acid. This reagent is being replaced in laboratories by Dess‑Martin periodinane (DMP), which has several practical advantages over PCC, such as producing higher yields and requiring less rigorous reaction conditions. DMP is named after Daniel Dess and James Martin, who developed it in 1983.

This page looks at the oxidation of alcohols using acidified sodium or potassium dichromate(VI) solution. This reaction is used to make aldehydes, ketones and carboxylic acids, and as a way of distinguishing between primary, secondary and tertiary alcohols.

Oxidizing the different types of alcohols

The oxidizing agent used in these reactions is normally a solution of sodium or potassium dichromate(VI) acidified with dilute sulfuric acid. If oxidation occurs, the orange solution containing the dichromate(VI) ions is reduced to a green solution containing chromium(III) ions. The electron-half-equation for this reaction is

Cr2O2−7+14H++6e−→2Cr3++7H2O

What is your opinion on marijuana?
jarptica [38.1K]

I think that marijuana should be legalized for recreational use.  It's not really bad for you and it doesn't cause problems like violence.  If marijuana was the most abused substance rather than alcohol it would be an improvement.
